I was having trouble getting this picture to be the right size, but the left hand side y axis has values of 50,100,150

X axis is labeled 2,4,6,8,10

The y axis represents distance in meters, x is time in seconds.

I am asked to order the following from least to greatest:

A. The instantaneous velocity at time 6 seconds.

B. The instantaneous velocity at time 9 seconds

C. the average velocity over the interval from 6- 8 seconds.

I know you can draw a tangent line for instantaneous velocity but this is hard for me to do with this picture.

How should I approach this problem? the average velocity appears to be about 5/2 but that's all I can get.

The correct answer is E and NOT A.

Answer E got cut off but it is B<C<A

This is an old quiz problem.

Can someone help me understand?
